SWITCH-THROW-ING DEVICE.

SPECIFICATION forming part of Letters Patent N 0. 706,668, dated August 12, 1902.

Application `filed March 4, 190,2.

To LZZ whom, it nur?! concern:

Be it known that I, THOMAS J. KENT, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, (whose post-oice 5 address is 36 Monongahela street,in said Pittsburg, county and State aforesaid,) have invented a new and useful Improvement in Switch-Throwing Devices; and I do hereby declare the following to be a full, clear, and

Io exact description thereof.

Myinvention relates to switch-throwing devices, and has special reference to such devices as are used in connection with railway, traction, and other cars.

The object of my invention is to provide a cheap, simple, and effective device for throwing switches from the car by the operator and during the movement of the same without compelling such operator to leave the car.

My invention consists, generally stated, in the novel arrangement, construction, and combination of parts, as hereinafter more specifically set forth and described, and particularly pointed out in the claims.

To enable others skilled in the art to which myinvention appertains to construct and use my improved switch-throwing device,'I will describe the same more fully, referring to the accompanying drawings, in which* Figure l is a perspective view of the end of a car and tracks, showing my invention applied thereto. Fig. 2 is an enlarged plan view of such tracks. Fig. 3 is an edge View of the switch-bar. Figs. 4L and `are ,views 35 of the pivotal connections for such switchf4 bar. Fig. 6 is a perspective view of .the casting-plate for the end of the switchbar, and Fig. 7 is a perspective View of the guide for the operating-lever.

Like letters and symbols of reference herein indicate like parts in each of the figures of the drawings.

The main tracks are shown at 1 and are provided with the throw-out tracks 2, connected 45 thereto by the switch-point I, which is pivoted at one end z', while its opposite end has a connecting-rod E, pivoted to a bearing 7l thereon and to one end c of a switch-bar C, and this switch-bar C is pivoted at or about 5o its center to a timber or plank B, laid between Serial No. 95,632. (No model.)

the tracks l, by means of a pin D, which passes through a bushing H in said bar C and plank B. The opposite end c of the switch-bar C is diamond-shaped, so as to form the inclined faces b h' thereon, and such end c rests with- 55 in the casting-plate A,which is placed between the tracks l at the end of the plank B and provided with upwardly extending inclined flanges a a' at each side thereof.

The end of a car is shown at 2, having the 6o platform 2" thereon and which extends from the end of the car in the ordinary manner and forms a portion of the floor 3', while an opening or slot 3 is formed in said fioor 3 on the platform 2, over and within which is 65 placed and secured the guide G, and this guide G is provided with the two pockets g g' thereon, formed by the inclined central portion g2 therein. The operating-lever F is pivoted atfto the bottom of the floor 3' and 7o extends up through the guide G, said lever F being provided with a spiral spring 4, connected thereto and to the bottom of the Iioor 3', while its lower end is provided with the shoe F,l1aving theinolined faeesff2 thereon. 75

The use and operation of my improved switch-throwing device are as follows: The switch-point I and the bar C being in the positions shown in Figs. l and 2, with the car approaching the same in the direction of the 8o arrow, Fig. l, and it is' desired to continue the movement or travel of the car along the main tracks 1, all that is `necessary is for the operator to grasp the upper end of the levert F on the end 2 of the car and throw said le- 85 ver into the pocket g of the guide G, which will cause the shoe F on the lower end of said lever F to be directed by the flange 0a to come in contact with the inclined face b onthe end c' of the bar C when the end 2, ofthe car 9o reaches the position over the end c', and after the end F passes the face b the operator can release his hold upon the lever F, and the spring 4L will return the lever F to the position shown in Fig. l, which will'cause the end 95 c' of said bar C to move to one side in the direction of the arrow, Fig. 2, and cause its opposite end c to move in the opposite direction by means of the pivot-pin D in said bar C, when by reason of the rod E being con roo the car to grasp and throw the lever F into the pocket g of the guide G in the licor 3 on the other side of the central portion gZ from the pocket g, which will cause the shoe F on said lever F to be directed by the flange d to come in contact with the inclined face b on the end c of the bar C when the end 2 of said car reaches the position over the end c', and

after the end F passes the face Z) the operator can release his hold upon the leverFand the spring 4 will return the lever F to place, as shown in Fig. l. This will cause the end c of the bar O to move toward the arrow shown in Fig. 2 and` cause its opposite end c, with its rod E connected thereto and to the free end of the switch-point I, to move in the op-b posite direction through the pivot-pin D and so act to move said point I to a position against the main tracks 1, which will enable the car to pass from the main tracks l onto the side tracks 2. The spiral spring 4, connecting the lever F and platform 2, will keep said lever clear of the track and switch-throwingparts when not in use, and the inclined flanges a on the casting-plate A will assist in directing the shoe F' on the lever F against the inclined'faces b b on the end c of the switch-bar C.

Various 'modifications and changes in the construction, design, and arrangement of the various parts of my improved switch-throwing device may be resorted to without departing from the spirit of the invention or sacricing any of its advantages.

It will thus be seen that my improved switch-throwin g device is positive in its movements and can be convenien tly operated at will by the operator from the car, and its use will permit the switches to be thrown to their positions without the operator being compelled to'stop or slacken up the movement of the car.
